Liver and Biliary Flashcards
List the types of Jaundice
- Pre-hepatic
- Liver jaundice
- Biliary Jaundice
What is pre-hepatic jaundice
Excessive amount of bilirubin presented to the liver due to excessive haemolysis
How is pre-hepatic jaundice detected in the serum
elevated unconjugated bilirubin in the serum
What hepatic jaundice
Impaired cellular uptake, defective conjugation or abnormal secretion of bilirubin by the liver cell
How is hepatic jaundice detected in the serum
Both conjugated and unconjugated bilirubin may be elevated in the serum
What is biliary jaundice
impaired excretion due to mechanical obstruction to bile flow
How is biliary jaundice detected in the serum
Elevated conjugated bilirubin in the serum
